of self-esteem than women, but that
gender gap is more pronounced in
industrialized nations, according to
research by University of California,

diners who ordered their dinners from
heavier wait staff ordered 17 percent
more alcohol and were four times more
likely to order dessert (Environment and
Behavior, online Dec. 28).
